Key Steps in the Factory Construction Process

The factory construction process involves stages from surveying to completion, ensuring adherence to safety, environmental, and technical standards for optimal project quality and investment returns.

Site Survey and Construction Planning

The initial stage in the factory construction process involves surveying and planning, comprising site assessments, ground condition evaluation, and layout analysis. Engineers propose design solutions aligned with architectural and technological requirements, focusing on foundational, infrastructural, and safety standards, particularly environmental and fire safety protocols.

An efficient site survey and construction planning step determines the project’s smooth progression, fully compliant with all construction standards.

1. Development and Approval of Survey Plans
   • The survey mandate must be meticulously prepared, considering project type and technical requirements, typically handled by the design contractor.
2. Technical Survey Planning and Approval
   • The plan features specif` The technical approach and relevant standards are crafted by the survey contractor, adhering to set objectives.
3. Construction Survey Implementation
   • Activities like data gathering, surveying, and geological examinations ensure comprehensive data integrity.
4. Acceptance and Approval of Survey Results
   • Results must be formally validated per protocol, adhering to all technical requisites.

Main Components of a Technical Survey Plan

• Planning Basis: Established on articulated mandates and geotechnical site surveys.
• Work Component and Volume: Detailed listing of required tasks.
• Methodologies and Equipment: Strategic selection of tools and procedures for optimal survey efficiency.
• Technical Standards: Strict compliance with technical regulations to ensure accuracy and safety.
• Project Execution Organization: Clearly delegated roles among the team members.
• Execution Schedule: Definitive timeline and sequence planning.
• Safety Measures: Prioritize environmental and occupational safety protocols.

Survey Objectives and Scope

• Objective: Ensure the facility’s design and construction adhere to investor standards and specifications.
• Scope: Applicable to construction projects spanning from minor to major scales.

Types of Surveys

• Geological Survey: Assess geological conditions and related phenomena.
• Hydrological Survey: Detailed hydrological analysis of the site.
• Geophysical Survey: Apply advanced tools for precise parameter acquisition.

To assure project success, the survey process and project plans must strictly conform to current standards and legal requirements.

Technical Design and Execution Planning

Technical design and execution stage focuses on detailed structural, foundational, and critical component designs. The application of QCVN standards ensures designs are aligned with local ground conditions and are safe, sustainable, and cost-effective.

Technical design and execution planning play pivotal roles in construction and energy sectors, particularly with QCVN standards to assure safety and effectiveness.

Technical design transforms initial plans into actionable solutions, ensuring all engineering and material solutions, like steel structures and foundation plans, comply with current standards. This includes selecting precise building materials and techniques suited to specific regional and environmental construction contexts.

Execution planning follows, offering detailed drawing documents that translate entire technical details and specifications, key to executing the project accurately from foundation to complete technical structures.

The construction design process highlights three primary steps:

1. Conceptual Design: Preliminary design concepts are established, creating the foundation for forthcoming phases.
2. Technical Design: Elaborate on technical elements from the conceptual design, integrating material selection and requisite technical standards in preparation for execution.
3. Detailed Construction Design: Delivers comprehensive drawings embodying all technical parameters and materials, guiding precise execution on-site.

Ensuring accuracy and safety in technical execution planning is crucial for the project’s successful completion while laying groundwork for cost estimation.

Adhering strictly to design processes and executing technical controls are pivotal to each project’s success, assuring technical and economic efficiency.

Design Approval and Permit Application

Securing design approval and construction permits is a crucial stage in factory building. This process involves submitting design documents to relevant authorities for evaluation based on technical, fire safety, environmental, and construction planning standards. Necessary documents include Investment Certificates, land use deeds, and other safety-related papers. Obtaining local government construction permits is imperative before project commencement.

In construction processes, design approval and permit acquisition are essential to ensure legal compliance and project safety.

Construction Design Steps

Design processes can vary from single to multiple steps, adapting to the project size and specifics. The three-step design approach includes:

• Conceptual Design: Establish initial plan, functionality, and basic technical solutions.
• Technical Design: Detail the conceptual design, define specific construction techniques.
• Execution Drawings: Deliver detailed drawings for construction facilitation.

Investors must prepare comprehensive design files, generally outsourcing this to professional contractors through contractual engagements.

Design Assessment and Approval Process

Required design documents include descriptive design, design drawings, survey data, construction estimates, and specifications. Design evaluations are executed by local expert agencies adhering to stipulated timelines:

• 40 days for Level I and special constructions.
• 30 days for Level II and III constructions.
• 20 days for other constructions.

Procedures must align with the 2014 Construction Law and guiding documents such as Decree No. 15/2021/ND-CP and Circular No. 18/2016/TT-BXD.

Post-Approval Design Adjustments

Approved designs may be altered only if project changes occur or quality and efficiency improvements are needed. Adjustments impacting significant technical parameters require re-evaluation and re-approval.

Construction Permits

Construction permits are indispensable, assuring project adherence to approved designs. Investors need to compile an application, including construction permit requests, design drawings, and land use verification. Certain circumstances under the 2014 Construction Law allow for permit exemption.

Major Legal Basis

Design approval and permit application processes rely on critical legal documents such as the 2014 Construction Law, Decree No. 15/2021/ND-CP, Circular No. 18/2016/TT-BXD, and Decree No. 59/2015/ND-CP.

Construction and Completion of the Factory Project

Construction and finalization encompass various stages from site preparation, foundation work, structural setup, to auxiliary support installations. Execution must adhere to the verified plan, utilize high-quality materials, and incorporate safety and environmental measures. Progress and quality control at each stage are crucial to ensure the final output meets specified standards.

Executing and completing factory constructions is intricate, requiring precision for quality, safety, and economic efficiency. Key stages and focal points during execution include:
